Joulethief SEC exciter and variants

[slayer007]

In this video I'm using the same circuit I posed in my previous video.
I'm not sure if you can adjust the SRF of all three coils at once because adding another coil changes the SRF of the first.
But if all three coils had the same load and would light at the same time.
The SRF might be close enought to fine tune them one at a time after getting them close to SRF.

Hi all,

I may have run into a significant discovery when working on my longitudinal antenna for my moon-bounce project, which appears to also connect to the Tesla Tower:

I am just thinking about Tesla's Wardenclyffe tower, after printing the so-called Anderson drawing:

Wardenclyffe Tunnels Investigation

<snip>

(high res version here: http://www.tuks.nl/img/Anderson%20Drawing.jpg )

<snip>

An interesting detail on this Anderson drawing is that the mains power is fed to the bottom of the shaft, suggesting that the transmitter transformer must have been positioned at the bottom of the 120 feet deeo shaft, a shaft that has been plated with iron.

This suggests that the shaft may have functioned similar to a sleeve / bazooka balun as I use in my longitudinal dipole antenna:
http://www.energeticforum.com/renewa...tml#post172852

Such a balun is essentially a short-circuited transmission line:

Antenna Theory - Bazooka Baluns

The green sleeve in Figures 1 and 2 acts as a transmission line, that is short circuited at the end. From Gauss's law, it is (basically) true that the current on the inside of the outer arm of the bazooka (green line) must be the opposite of that flowing on the outside of the coax (grey line). Hence, the current IC actually sees a short-circuited transmission line. If the length L of the sleeve is chosen to be a quarter-wavelength (at the desired frequency of operation), then the impedance that the current IC sees is infinite (this is the principle of a short-circuited quarter-wave transmission line - see the impedance page for a brief introduction to transmission line theory).

So, if you think away the coax core, then you would essentially have a structure that keeps the current (== magnetic component) above the bottom of the shaft in Tesla's case and therefore the only component that can propagate along the 300 feet 1/2 lambda iron "earth grip" starting at the bottom of the shaft would be a longitudinal dielectric wave....

<snip>

And it appears this principle might also apply to the Gray tube:
http://www.energeticforum.com/renewa...tml#post174297


What this is about is the principle of how to get an antenna or coil into a longitudinal resonance mode. While for the antenna the problem was how to feed the signal from the coax feed into the antenna, with resonating coils the problem is how to get rid of the magnetic component, the current.

I think the same principle, a bazooke/sleeve, can be used in Joulethief / SEC exciter circuits. After all, a coil can be considered to be very similar to an antenna. It is mostly very much shorter.

So, the idea is to mount a coil like Slayer's on top of a copper plate, like a PCB, which acts as a reflector, and connect the coil to the copper plate. There would be two taps in this coil, one at 1/4 wavelength and one 1/2 wavelength further on, which is driven using a Hartley oscillator circuit, as I posted before:
http://www.energeticforum.com/renewa...tml#post148514

From the point where the emitter is connected, a second coil is wound on top of the long one, which has (about?) the same number of turns and is wound using the same wire. The connection near the copper reflector is left open, just like the green sleeve in the above balun illustration. According to the balun theory, the diameter of the short sleeve coil should be like 2-4 times the diameter of the small, long coil.

I have made the following drawing to illustrate this:

Hi-res version: http://www.tuks.nl/img/Lamare_Sleeve_Coil.jpg

The funny thing is that when the coil is in resonance, the currents trough the sleeve coil and main coil are in the opposit direction, wich gets rid of the magnetic component of the propagating wave and you should end up with a longidudinal dielectric wave traveling along the length of the coil. This wave propagates by means of capacitive coupling between the coil windings in a direction perpendicular towards the coil windings. And it propagates with a speed of pi/2 times the propagation speed of transverse waves, which is why you get particular longitudinal and transverse resonance modes in both coils and antenna.

At the moment, I don't have much time to experiment with this, because I am concentrating on my moon-bounce project. But may be one of you feels like playing with this...

Update: It may be that the sleeve coil will have to be wound in the other direction as the main coil (clockwise vs. counter-clockwise), as Kapanadze did. I don't think so, because the two coils make a 1/2 lambda dipole together, but Im not sure.

[kcarring]

Well, I messed up my coil, and fried my last high gain MPSA06, so I'm down for a bit on this game... but have 100 more on order. I went through 36 transistors to find that last one, but I messed up trying to make it into a high output complementary, fried it. I'm also going to try the 2N5551. It might need to be run in Darlington tho.

Interestingly, when my circuit was in resonance, I was using my variable capacitor, and it was somewhere in the 100-115 pF range that it tuned up. At that point, increasing the capacitance beyond about 115, detuned the circuit, and certainly there was decent output at points above, for example @ 800 pF (close to your value) or 1nF.. but... the real magic happened at that 115 pF. Now, once the pigtail was cut... there's nothing in that lower cap range, and only mediocre output available by "pushing the capacitance". This leads me to believe that I was playing in a "node" as the Dr. speaks of. Further evidence of this was that I was able to get high plasma of about .75cm off the pigtail, at only 20 mA and a strong brightness on the bulb. Also, plasma @ 9v. At this "magic point" even my hand 12" away from the setup would effect the circuit, it was really quite interesting. Even where I place the variable capacitor, itself, in it's distance from the main coil, played a factor. Believe it or not, even where I attached the -12v lead of the croc lead to the breadboard, it's position on the rail.. closer to the Vcc, further from Vcc (where it actually joined the rail..." EVEN THAT affected it, suggesting I was tuning the breadboard itself. I could light 2 bulbs to a brightness level @30 mA, I cannot achieve with 60-70 mA now. While completely unproven, and not being qualified to say really, again, I feel I was on a node... but it just as likely it was only self resonance. I wonder though, because I witnessed BLASTS of output I never managed to film... it got me so excited I'd run and get the cam but then it'd taper off. Very strange. Output at 30 mA (12V) that lit up the room to a typical 2 watt level, but just for a moment. Who knows. Wish I had of filmed it better. And as Raui and The Dr. have shown, it's not always where the peak is.. the peak can even lie sometimes (spectrum analyzer). So maybe I'm clueless, maybe I was lucky, maybe it was nothing at all.. I can't honestly say, BUT.. the one thing that is for certain, and was a real interesting aspect, is, that.. the circuit, when it was operating real well, was literally "alive" to play with, a first for me, and quite interesting indeed, when comparing it to how it behaves now. It was like a field of capcitances, every minor movement, placement, taking effect..sometimes producing results that gave off light not previously seen at less than a watt. At 1/3 of a watt. And although completely unscientific, I have 75 videos of light under a watt... I've grown to know what a typical watt of light, in this room, at night... looks like! Anyway it was fun. Time to look at this again, on a scope, signal generator... I'm a math kinda guy, I have to have a piece of wire and measure it out in length and weigh it on a scale. Get it away from all the monitors, RF sources... clutter.. mess... this sort of thing deserves better work practice than I've given it... it was pathetic really, I'm sure the Dr. would shake his head muttering "what a bozo" -- if he saw it, but hey whatever... I'm a noob. He's a scientist. I'll bet he cant cut down a 275 ft. Douglas Fir without killing himself, either, and I can!!! hahha. With all due respect to him though.. Hat's off, I truly believe there is something there... I tend to think I may have only been self resonance, but, I also look at his circuit, and ask myself.. how is that truly possible.. because there is no capacitance in parallel with a primary inductor as in a Slayer or Tesla Coil. I want to see this effect on a meter, somehow... I can't do the random thing forever, I got a 3 yr old kid that deserves my time more than that behaviour does (my "random" stabs at this, I mean), if you know what I mean... LOL. Not to mention 1800 watts of solar panels that need to be made to track the sun!! That's a guaranteed 100 watts of extra free energy, right there... This technology can get good though, I'm pretty convinced!!!! I've had a taste.. I hope someone can take it to the level it NEEDS to get to, to be viable. Reproduceable without 3 devices that cost $3000 that consume 40X the energy being captured, running... It's phenomenal, but far from practicle, at this point. A $100 solar panel still has it beat. Then again, a $100 solar panel has every technology on this whole forum beat, if you ask me. But this one is very very very intriguing, nonetheless. I believe this one could be much more scalable. If you look at what the Doctor is doing, he is dropping in size, and increasing in output... that is a very good trend... very good indeed. Scalability is not all about building enormous, for bigger gain....at all. In fact, that is where you lose scale. Nobody needs 100 ft tall 20 watt wind turbine, for example.

cheers mates

Thanks for that info

[slayer007]

Great work by all !

@Slayer - I can see the meter is a Craftsman, but could you tell me the model number ? I'm seeing vast pricing differences for seemingly similar meters. That's a great method you showed.

Kyle and Jonny - this stuff is awesome (as they say). Whereas people normally study the tiny intricacies and some are heading toward self running...you guys are unexpectedly blasting power out !


I hope this is relevant, from personal observations with self made SEC 18's. Running ability and output can be exactly the same from 1.2V as from 3.7V. That's quite the change in voltage and, maybe, you guys could try lower voltages but change capacitances etc, with the goal of plasma attainment ?

I just goofed majorly, yet found something out which may have use.
Yesterday I discovered a few 2001 vintage laptop battery cells in the shed and charged one for an hour this afternoon, on a self made 3 coil Bedini wheel. 3.7V Li-Ion. It charged well, so I thought i'd try it on a SEC 18, that was made from junker parts on a CRT monitor.
I connected the battery the wrong way around, quickly realised and removed the cell. The Green LED (normally white) on the circuit flashed ! It did so a few times with repeated connects/disconnects, until I decided it may not be healthy for the circuit.
So, these circuits are indeed vastly different to our usual ones...so much to discover.

The meter is a Craftsman Pocket Multimeter 82351.

Replication of Kyles Sec exciter plasma discovery

Hi Kyle .I had to try and replicate your plasma discovery and struck lucky.
I changed the L3 to a very small 4cm coil which I had previously used for a ferrite slayer exciter and it did not work but the free end of the coil seemed exceedingly long so i cut four inches of it and she fired up.
The meter was reading 32mA when it started emiting plasma so I cleared stuff away from around the coil it had gone up to 60mA which is still amazingly low for plasma.
I am using a 10uh choke inductor for both L1 and L2 with a magnet for tuning on L2.I think the reason why the magnet did not work for you is yours is in tune from the get go but mine is not.
I think everything has to be just right for this to work but I am very happy to have seen plasma from this circuit and such a small coil.Many thanks.Jonny.

@Slayer.Hi That circuit is great and pure gold for those trying to replicate the Dr's PSEC where srf of the coil seems to be the major stumbling block.The output looks really good too and I will try it as i would like to get involved with the psec too but have no equipment or the knowledge to use it.
Probably worth cross posting to the Dr Stiffler SEC thread.
Thanks for sharing.Jonny.

[slayer007]

@ Kyle
Some Great videos Kyle,It looks like your off to a good start.

For this test I'm using a Dr Stiffler type circuit to find the SRF of a coil.
This will work with very large coil and also very small coils.
You will just have to retune it with the ferrite rod and the varitable capacitor.

Off a AA battery this will run from 70uA to 30mA.

[jonnydavro]

Hi Kyle.Firstly I would like to thank you for a great series of vids and also Dr Stiffler for the Sec exciter circuit .
In your vids you show how important component choice and tuning are and how much time you have to spend to get results but I am so glad that you stuck at it but I don't think you can pack it away just yet as as far as I am aware,in vid no 5,you have the only plasma producing Dr stiffler based Sec exciter on the planet so we need to find out what are the factors which make your build different so this can be replicated.
Can you build another one so as not to risk losing the configeration that works?
Can you see if it will work of a wall adapter with its noisy DC.?
Is the non connected Slayer L1 playing a part?Don't remove the one on your working coil to find out,best to wind another L3.
Can you get plasma with a variety of L3 coils or just the one you show?
Is component placement a factor,try reverting back to the Doc's original design with the capasitor of the base and L2 inductor to battery negative.Do you still get plasma?
Will it work without the variable capasitor?
Are you using earth ground?Does removal stop plasma?
What happens when you add an Led protection/indicator or diode?
Your 22uh potted inductor may be vital,I wonder if it is identifiable and still available?
Could you possibly post a circuit diagram here for reference?
Sorry for all the questions Kyle but you do have something different and unique as far as I am aware and I would hate for this to get buried and not developed.Really nice work and thanks for sharing.Jonny.

(Replication) Jonnydavro's SEC 15 Variant - 12V / 75 mA - 15 Watt 18&quot; Fluoro

Happy New Years to all ya great people! Here is a run at replicating jonny's SEC 15 fluoro variant, just a start. I am finding it rather difficult, but then again, this is my first shot at anything originating from the Dr.. anyhow, I did get some results, but a lot of fine tuning before I'll see the magnetic effect I suppose. Thanks to the Dr., jonny, Lidmotor et all.

Very fun balance of capacitances, tricky for me!

Cheers, Uploading right now, may take a bit.

(Replication) Jonnydavro's SEC 15 Variant - 12V / 75 mA - 15 Watt Fluoro - YouTube

Interestingly, about 5 mins. after I wrote this, I disconnected the circuit, reconnected it, bumped a wire, inadvertantly, and my draw went up to about 130 mA, light output doubled.. What an amazingly sensitive circuit.

wow.. ok... i get it... the fluoro cant be too close to the coil! bizarre! So for fun, i added a floating L4 connected to nothing at all, and it effectively increased the range of the circuit enabling a second 18" bulb to be lit, and even lowered the draw, some:

(Replication 2.) Jonnydavro's SEC 15 Variant - 12V / 75 mA - 15 Watt Fluoro - YouTube

I also noticed if you touch the output wire, it begins to give off a tiny plasma flame too.

I decided to add another coil, attached to the base, just like the main coil was (L1 in jonny's vid) but I couldn't get it to go. So, I wrapped a sort of primary-like wire around one of the L1's, then a croc lead to a stationary aluminum block that I moved around and adjusted a bit. I'm not sure if it is acting as a feedback, or if it is a capacitance coupling, but it synchronizes everything and is quite interesting in that it allows for the bulb to be more evenly lit across it's length, and gives pretty good output at 80-100 mA/12V.

(Replication 3.) Jonnydavro's SEC 15 Variant - 12V / 100 mA - 15 Watt Fluoro - YouTube

In this video I add a second variable capacitor between collector and ground, change the L1 inductor to a potted ferrite 22uH, change the L3b coil to a much smaller air core and dimly light (2) 15 watt bulbs at 12.4V / 30 mA.

A better higher gain transistor, plasma, and 3 tubes running at about 20 mA

Added a virtual ground, repositioned everything horizontal for better control... 22 hours later, this is the best i can do. If I had of arrived at this, first try, I'd have never believed it. Not sure what the draw is, I can only guess cause it's less than a needle's thickness

Hi.Here is an experiment using a Dr Stiffler type sec exciter using fixed inductors for L1(22uh) and L2(10uh) and a hand wound small L3.
The interesting thing is tuning is done using a small neo cube magnet on the 10uh L2 choke.
You can tune for maximum output or if you position the magnet just right you can set up what seems like a secondary oscillation.Here is a vid which shows some of the weird effects.Jonny.

If you find yourself some old power amplifiers at a yard sale/Freecycle, then you can go ahead and be just as retarded as you like !
Should be good for some parallel running of IRF series MOSFET's.
Make sure to have a camera running though and that we get to see it on YouTube

Oh, and, stand well back, fire extinguisher at the ready, disclaimer notice on the video and all that.
Personally, I would also recommend not firing this up on your computer bench, next to your expensive hi-fi etc.

In fact though, a few well sized resistors on the front and it could all be anticlimactic...but keep safe anyway.


To think of it one way, you could be 83 years old, sitting outside in a rocking chair and thinking 'I wonder what would have happened with that 96v Slayer hmmm'.
But, you have to counter that with getting to 83 years old in the first case

great advice!

I hearya on the safety precautions LOL I'll have the rubber gloves on. I have a handful of IRFP450's - I find them in old casino machines and medical monitering power supplies at the recycler. But.. those... I'm saving for my next >>biggish<< project a PWM for my 58 plate 110V HHO cutting torch / welder. Gonna revamp my 21 plates, Delvis11 style... that guys builds are nice!

I was thinking, I hope the CRTC Canada van won't be cruising around whilst my AM station is buzzing LOL Some big fines for that I hear...

I have to figure out how to put together a high voltage PWM. (I believe Tesla called it a spark gap )))))

Sure is workin nice on the Incroyables Flip Flop, pleased as punch there!

[jimboot]

Very sage advice @slider
